Hey guys first post here, found it browsing the net. I figured I would share my bike and give info if anyone wanted it.

Its an 83GPz750, about 25k on the clock. i put a 95 gsxr750 bracked swingarm. 5.5" rear wheel with metz rennsport 180 on it. up front i put a 90 gsxr750 front with 17" wheel, rennsport up front also. ive got 6 pot tokicos up front with full floating rotors, braided lines, 6 way adjustable lever with remote res. graves clipons under the top tripple. fox shock in the rear. KN indiv pod filters. kerker 4-1. atleast thats how it was in the picture :twisted: It dynoed at 80hp rear wheel when i had stock wheels and suspensions on it with the exhaust and K&Ns and 630 chain. Ive since done a little jet work and 530 conversion and a few other things.

its got 22.9 degree rake angle, 3" trail 54 degree lean angle, 24 degree swingarm angle, about 55" wheelbase.

the pics are rather large so ill just link you to them

how it used to look in 99 when i bought it

if you guys have any questions or want any more info let me know. I did a complete write up on switching over including everything I had to do and all the custom parts I had to make.

Thats a very sweet bike, plenty of mods too.

Very interested in what all had to be done to use the gsxr swing arm and forks. Did you have any trouble getting the front and rear sprockets to line up?
Hell, I bet it feels good just to have a wide selection of tires....lol.

it wasnt all that involved but thats me

Well for the front(the easiest part) i custom made a stem and that was it really. besides the headlight bracket. What i did with the stem was tool an extra one i had from a gpz/kz and i use a tig to add filler to the base of the stem. Then i turned it down on the lathe and left a few grooves in it, as well as a lip at the bottom(gsxrs had a cclip on the bottom, lip did the same thing) i miscalculated by a 1/16th so i ended up shimming the lower bearing but all it fine.

The rear end wasnt bad but more indepth. I made a front sprocket, its 5/8th offset. I took a zero offset and milled out the center, used a short piece of sch40 pipe and tacked it back together several times while turning it on the lathe to ensure it was square(took forever). the swingarm was actually not as wide at the pivot so i just made some very small spacers. it was 1/8th total i think. but i did have to file it down a bit because it had a larger diameter and rubbed the case in 3 spots. the pivot axle worked good. gsxr swingarm had two inner races, i pulled the inner most one out and voila, the gpz race was the same od as it, just the id to match the current swingarm pivot axle. now the linkage is where it got tricky. the gsxr linkage mounted to the top of the swingarm in 95(changed in 96) but the gpz mounted to the lower. So i fabbed up some linkage to get the right frame attitdute i wanted. First set was 6061 but because of limited space i wasnt able to make it strong enough so now there is a steel set on there. Since i put a 5.5" rim on instead of the 6" rim i had a little more room to play with but the wheel is inline with the front. I had to actually space the rear sprocket out a small amount. I have equal room between the frame and the tire with the 530 oring chain, if i went to a non oring i could fit a 6" rim with a 190 on it pretty easily.


and yes the sticky 180 is way better then the 18" 130, but i will say it did a burn out way better before but now it will wheelie. :twisted:
